Which components is faulty?

[JakubPavlat]

Hello,
I am having some issues with my sister's computer. Her system crashed a few days ago, and because all the hardware is fairly old, I swapped my motherboard (with a CPU and RAM) with my old one. They are identical.

Core 2 Quad 9300
RAM 4GB Corsair DDR2
Intel DQ35JOE MB
NVidia 9800GTX

What was left the same is a PSU unit (450W Eurocase that came with the tower) a WD HDD 500GB 5400rpm and a DVD drive.

Even after the swap her system keeps crashing -

so far only during gameplay and I have also tried an nvidia demo and it crashed as well. I have tried CPUID HW monitor, but everything goes well until it crashes and I cannot retrieve any data, because I have to reboot.I took a picture with my cell, that is how it looks after crashing.

I wonder if it is the PSU (I know that an eurocase that came with the tower is not exactly good for gaming) or whether it is a HDD problem or something else.

If anyone has any idea what could be wrong please let me know
I really appriciate any help

So you get any POST beeps when turning the PC on?

well yeah under load like that first thing I would want to start looking at is the power supply and the 9800.. that looks an awful lot like some bad/fail nvidia card glitches/freeze/crashes though... I wouldn't trust HW at all...., get into the bios and check out what rail voltages are...could be pretty bad under load...

@Kavster001 No, after I am promted whether I want to boot regular Windows or the emergeny mode (or what it is called) for all I cat tell, the system is running just fine.

@JR1988 Is there any way to determine, which one is is? And how did it star having problems just now?

you need to see what the +12v rail is doing under load, use a meter/tap into the rail ATX specs is 5%ish so if its dipping below 11.5v or worse yeah could be a problem. even though I don't 11.5v would do that I would think it would have be way worse. A healthy PSU on the 12v rails isn't gonna drop much under load maybe to 11.7-11.8....
